According to CBS affiliate KEYE, the explosion occurred at the 4800 block of Oldfort Hill Drive in east Austin.
The report reviews bombing and explosives-related incidents and threats from information reported to the United States Bomb Data Center through the Bomb Arson Tracking System by its almost 2,500 interagency partners and 12,153 registered users, according to the report.
Making a bomb that works at the right time is harder than it might sound.
All of the explosives in Austin detonated while a victim was carrying them, and not while the suspect or suspects was placing them on the victims' doorsteps.
A package bomb that killed a teenager and wounded a woman in Austin Monday morning is possibly connected to two other bombings, including one that killed a man elsewhere in the city this month, investigators say.
Or the suspect is working with someone who does live in the Austin area.
The three bombings took place 11 days apart - March 2 and then two this Monday - but police have said that they believe they're related. However, Austin Police Chief Brian Manley has already said they will likely face a "lengthy investigation" moving forward. That the packages were left rather than being mailed indicates the bomber is local.
"The detonation of the device when it was moved could indicate the use of a remote detonator", the Stratfor report said, or the use of a triggering device such as a mercury switch - which is activated by movement.
If the bomb maker used a remote, it would have "required the bomber to have had visual contact with his victim - potentially exposing him to detection", the Stratfor report said.
